  • SILICONE HYDROGEL COMPOSITION AND SILICONE HYDROGEL LENS
    Publication number: 20230382066
    Abstract: A silicone hydrogel composition includes a first hydrophilic monomer, a siloxane compound, a first crosslinking monomer, a second hydrophilic monomer, and a second crosslinking monomer. The first hydrophilic monomer and the siloxane compound have an acrylate group or an acrylamide group and may also have a methacrylate group or a methacrylamide group. The first crosslinking monomer has a plurality of acrylate groups or acrylamide groups and may also have methacrylate groups or methacrylamide groups. The second hydrophilic monomer has a non-conjugated vinyl group. The second crosslinking monomer has a plurality of non-conjugated vinyl groups. A sum of the weights of the second hydrophilic monomer and the second crosslinking monomer is 40 to 100 parts by weight, relative to 100 parts by weight of the sum of the weights of the first hydrophilic monomer, the siloxane compound, and the first crosslinking monomer.
    Type: Application
    Filed: July 25, 2023
    Publication date: November 30, 2023
